MACHINE FOR MAKING CLAY SMOKING-PIPES.

SPECIFICATION formingpart of Letters Patent No. 272,966, dated February27, 1883.

Application filed July 11, 1882. (No model.)

To all whom it may concern:

Be it known that I, OLIVER J. MASON, of Tallmadge, in the county ofSummit and State of Ohio, have invented a new and Improved Machine forMaking Clay Smoking-Pipes, of which the following is a full, clear, andexact description.

Myinvention consists essentially of an endless chain of dies or moldsmoving intermittingly along a place for being charged,with the clay forthe pipes, another place where formers make the bowl and perforate thestem, another place where the molds open and discharge the pipes, andthence back to the place of being charged, together with the forming andactuating apparatus, the said machine being contrived for more rapidoperation and greater capacity of production than the machines now inusefor making pipes, all as hereinafter fully described.

teference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is partly a side elevation and partly a sectional elevation ofmy improved machine,.

and Fig. 2 a front elevation, partly sectioned.

I make one or more endless chains of square mold-blocks c, by hingingthe blocks together at b, and arrange these chains on square rollers c,for being moved along to receive the clay and mold and deliver thepipes. Each mold-block has two half-mold cavities, cl, in its twoopposite sides, the bowl portions of which open through the tops of theblocks and the stem portions atthe ends ofsaid blocks. These cavitiesbeing in the sides of the blocks that are hinged together, it followsthat when the blocks are passing along their course between thecarrying-rollers the cavities of the adjacent sides of the blocks formcomplete molds,

and when passing around the rollers at the ends of the course thejointsbetween the blocks will open so that the molded pipes may be discharged.These chains of molds, being geared by the four-armed wheel 6 to beshifted the breadth of one block at each revolution of the cran k-shaftfby an arm, i, thereon, are made to pass under the charging-spout h, towhich the clay is supplied by any approved means from the mill w, andfrom which the requisite quantity is driven down into the moldssuccessto be produced.

ively by the plungers j, attached to the crosshead It. From the chargersthe molds pass under bowl-formers 1, attached to crosshead 70, whichdescend into the charged molds and form the bowls at the same time thatthe plungers are charging the next molds. The crosshead also carriesinclined pushers m, which at the same time force in the stem-formers andperforators n, and they also carry bars 0, that pass down in the grooves29 in the ends of the mold-blocks and hold them against opening at thejoints by the pressure of the formers on the clay, each of the twoblocks of a mold be ing thus held at the same time. The stemformers andperforators are withdrawn by the coiled springs applied to them. Anyother approved device may be used instead for th at purpose. Theplungers are worked by the crankshaft f, to which the power is appliedby the driving-shaft'q and toothed wheels 7' .9. Where the molds opengoing around the right-hand roller 0, Fig.1, the pipes fall on endlesscarriers t.'which deliver them into any suitable receptacle. Thearm-wheel e is providedwith spring-brakes u, to preventitfroin beingthrown too far; but any other suitable stop device may be used. 1

In this exampleI have represented two chains of molds; but it is obviousthat more may be employed, according to the required capacity of themachine. The form of the molds may vary according to'the required formsof pipes In this case the molds of one chain are constructed for makingthe stems oblique to the bowls, and the others for rightangled bowls andstems.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a machine for making claysmokingpipes, a series of mold-blocks hinged together to form an endlesschain, and each having two half-mold cavities in its opposite sides,substantially as herein shown and described.

2. A series of mold-blocks hinged together to form an endless chain, andeach having two half-mold cavities in its opposite sides, the bowlportions of which open through the top and the stem portions at the endsof the blocks, substantially as herein shown and described.

3. The combination, with the series of moldblocks a, hinged together andhaving the moldaaaeee cavities d in their sides, of the rollers c, anmeans, substantially as herein shown, for operating said rollers, as andfor the purpose set forth.

4. The combination, with the series of moldblocks a, hinged togetherandhaving the moldcavities d in their sides, and the crank-shaft f,provided with the arm 11, of the rollers c, the four-armed wheel 0, andthe spring-brake 2t, substantially as and for the purpose set forth.

5. The combination of the holding-bars 0 on the cross-heads with thejointed pipe-molds having grooves 19 in the ends, substantially asdescribed. 7

6. The combination of the inclined bars m on the cross-head with thestem-formers n and the pipe-molds, substantially as described.

7. The combination of the endless chain of pipe-molds, rotating carriersfor said molds, arm-wheel for working the carriers, and an arm of theplunger driving shaft to work the said arm-wheel, substantially asdescribed.

8. The combination, with the series of moldblocks a, hinged together toform an endless chain, and having mold-cavitiesd in their sides, andmechanism for operating the same, of the endless carrier t,substantially as and for the purpose set forth.

OLIVER J. MASON.
